UNITED STATES PATENT OFFICE.

JOSEPH CALIXTE PELLETIER, OF WINNIPEG, MANITOBA, CANADA.

MUSIC-BINDER.

Application filed September 2, 1919.

To all whom it may concern Be it known that I, J OSEPH CALIXTE PELLETIER, of the city of \Vinnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Music-Binders, of which the fol lowing is the specification.

The invention relates to improvements in music binders and the principal object of the invention is to provide a binder in which sheet music and such like material can be quickly bound and which is arranged so that the bound sheets will lie flat when open, thereby rendering it not only easy to read the music but making it an easy matter to turn the music when one is playing.

A further object of the invention is to construct the binder in a simple, durable and efiicient manner and so that it can be manufactured and marketed at small cost.

With the above objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which Figure 1 represents a view of the binder as it appears opened up and with several sheets of music bound in it.

Fig. 2 represents a plan view.

Fig. 3 represents a side view of the binding parts.

Fig. 4: represents an enlarged detailed vertical sectional view through one of the fasteners.

Fig. 5 represents a perspective view of one of the fasteners partially open.

Fig. 6 represents an enlarged detailed plan view of several of the binding strips and the filler strips interposed therebetween.

Fig. 7 represents a perspective view of part of one of the binding strips with a fragmentary portion of a sheet of music fastened thereto.

In the drawing like characters of reference indicate corresponding parts in the sev eral figures.

1 and 2 represent stiif front and back covers connected flexibly to the back piece 3. This part of the construction is the same as practically any book binding work, it being only necessary that the back 3 be strong and stiff and that the covers amply protect the inclosed sheets when the binder is closed.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Serial No. 321,165.

To the inner face of the back 3 I secure a plurality of similarly constructed fasteners 4- each of which comprises an outer receiving sleeve 5 permanently secured at 6 to the binder back and an inner sleeve 7 which is designed to telescope more or less tightly within the sleeve 5. One end of the sleeve 5 is supplied with upstanding flanges 8 and the opposite end, so to speak, of the sleeve 7 is fitted with similar outstanding flanges 9. These flanges serve to act as a binder for the strips placed on the outer sleeve, this being more fully explained hereinafter.

In the present instance I have made the sleeves of a triangular shape but I wish it to be understood that I do not desire to be limited to this particular form as they could be made of any other irregular shape which would hold the binding strips in place once the strips were applied thereon.

On the sleeves I place binding strips 10 and filler strips 11, the filler strips being simply fiat rectangular cardboard pieces serving to space the binding strips. The binding strips are somewhat wider than the filler strips (see Fig. 6) and they are each made from a single piece of material folded lengthwise and with the edges brought together. Both the filling strips and the bind ing strips are provided at their rear edges with spaced notches 12, there being a notch for each fastener and with the notches all formed to receive the outer sleeve of the fastener. Actually the binding and filling strips are placed on the fasteners by threading them on to the Sleeves 5 after the sleeves 7 have been withdrawn and they are afterward held in position by replacing the sleeves 7 and shoving them in tightly so that the said strips are held from moving 05 endwise by the flanges and from pulling off by the triangular shape of the sleeves and the notches.

The sheets to be bound, such as music sheets 13, are sewn to the binding strips as indicated at 14, the sewing being preferably a long stitch so that it will not cut readily.

When one wishes to insert a music sheet in the binder he takes a binding strip and opens it up and then sews the music sheet to it. When this is done he folds the two edges of the binding strip together and puts the binding strip on the sleeves 5 in the manner hereinbefore disclosed, the binding strip being held in place after the sleeves 7 have been closed in.

lVith this arrangement I have found that the sheets will lie perfectly flat when open and have no tendency to turn back or close as customarily occurs in bound music.

What I claim as my invention is 1. The combination with front and back covers and a back strip connecting the covers, of telescoping fasteners secured to the back strip and each presenting'a pair of opposing end flanges, binding strips held to the back strip by the fasteners and received between the end flanges and music strips fastened to the binding strips.

2. The combination With front and back covers and a back strip connecting the covers, of a plurality of similar fasteners secured to the back strip and comprising each a pair of telescoping sleeves fitted with end flanges, a plurality of binding strips mounted on the sleeves and prevented from end displacement by the flanges and music sheets sewn to the binding strips.

3. The combination with front and bacl: covers and a back strip connecting the covers, of a plurality of similar fasteners secured to the back strip and comprising each a pair of telescoping sleeves triangular in cross section and fitted with end flanges, a plurality of binding strips mounted on the sleeves and prevented from end displace ment by the flanges, said binding strips being each formed from a single strip folded lengthwise and with the two edges provided with triangular apertures and brought to gether and music sheets fastened to the folded edges of the binding strips by sewing.

' Signed at Vinnipeg, this12 day of August 1919.
